Description

液晶显示模组 技术领域
本发明涉及液晶显示器领域, 尤其涉及一种可以提高视角特性的液晶 显示模组。 背景技术
液晶显示装置 (LCD, Liquid Crystal Display )具有机身薄、 省电、 无 辐射等众多优点, 得到了广泛的应用。 现有市场上的液晶显示装置大部分 为背光型液晶显示装置, 其包括液晶面板及背光模组 ( backlight module ) 。 液晶面板的工作原理是在两片平行的玻璃基板当中放置液晶分 子, 两片玻璃基板中间有许多垂直和水平的细小电线, 通过通电与否来控 制液晶分子改变方向, 将背光模组的光线折射出来产生画面。 由于液晶面 板本身不发光, 需要借由背光模组提供的光源来正常显示影像, 因此, 背 光模组成为液晶显示装置的关键组件之一。 背光模组依照光源入射位置的 不同分成侧入式背光模组与直下式背光模组两种。 直下式背光模组是将发 光光源例如 CCFL(Cold Cathode Fluorescent Lamp , 阴极萤光灯管)或 LED(Light Emitting Diode , 发光二极管)设置在液晶面板后方, 直接形成面 光源提供给液晶面板。 而侧入式背光模组是将背光源 LED 灯条(Light bar )设于液晶面板侧后方的背板边缘, LED 灯条发出的光线从导光板 ( LGP , Light Guide Plate )一侧的入光面进入导光板, 经反射和扩散后 从导光板出光面射出, 在经由光学膜片组, 以形成面光源提供给液晶面 板。 普通的 TN型液晶显示面板一般采用的液晶材料是 P型具有正介电特 性的液晶材料, 在非加电的情况下, 液晶分子平行于液晶显示面板的两相 对基板, 相邻的液晶分子彼此独立排列。 随着 TN型液晶的发展, 依然有 一些问题有待解决, 比如: 观看高对比度图像时的对比度缺陷。 另, 普通 的 VA型液晶显示面板一般采用的液晶材料是 N型具有负介电特性的液晶 材料, 在非加电的情况下, 液晶分子垂直于液晶显示面板的两相对基板, 且分别在两基板的表面上加有偏振片。 这样的液晶显示器件很容易获得 TN 型液晶显示面板不可得到的较高的对比度。 在加电提供电场的情况 下, 液晶分子大体上是处在和基板平行的液晶平面上, 同时背光源的光线 经过偏振片的偏振光将会通过已经旋转的液晶分子。
但是如图 1 所示, VA型液晶显示器件中的液晶分子在不同的观察角 度上表现出的不同的对比度, 如图中分别从 A、 B及 C三个角度进行观察 得到不同的对比度 a、 b及 c, 从而导致视角特性降低。 在发展潮流中, 基 板尺寸不断变大和响应时间不断减少的情况下, 提高视角特性, 已经成为 VA型液晶显示基板的一种需求。 发明内容
